Fix open/fopen in thread other than main

Before this patch, calling Volume.{f}open in a thread other than main
thread was causing segmentation fault (test included).  The reason is
missing ctypes declarations.

Also, this patch fixes errno handling for these two functions, making
couple of FIXME/TODO notes go away.
